/***************************************************************************
Homelab driver by Miodrag Milanovic
31/08/2008 Preliminary driver.
15/06/2012 Various updates [Robbbert]
The emulator called HoLa! works fine, but it is closed source.
You can get HoLa! at: http://gaia.atilia.eu
ToDO:
- HTP files should be a cassette format, not a quickload.
- homelab2 - cassette to fix.
Note that rom code 0x40-48 is meaningless garbage,
had to patch to stop it crashing. Need a new dump.
- homelab3/4 - Need a dump of the TM188 prom.
cassette to fix.
up to 64k ram can be fitted. schematic only shows 16k.
Z80PIO - expansion only, doesn't do anything in the
machine. /CE connects to A6, A/B = A0, C/D = A1.
The bios never talks to it. Official port numbers
are 3C-3F.
- Brailab4 - same as homelab3.
- Braiplus - no work has been done. Needs to be developed from scratch.
TM188 is (it seems) equivalent to 27S19, TBP18S030N, 6331-1, 74S288, 82S123,
MB7051 - fuse programmed prom.
